PGM recovery from catalytic converters

PGM recovery from catalytic converters

A breakthrough approach to recovering Platinum Group

Metals (PGM) from the spent automobile and chemical

catalysts

Catalytic converter (automotive)

Up to 2-4 kg of PGM/ton

A catalytic converter is a vehicle emissions

control device that converts

toxic pollutants inexhaust gas to less toxic

pollutants, by catalyzing a redox-reaction

(oxidation or reduction)

Basics

Platinum metals (Pt, Pd and Rh) Recoveries

Our company offers recycling process to recover Platinum Group Metals (PGM) from

automotive catalytic converters, and other waste streams in a sustainable and environmentally

friendly way. The PGMs are then reintroduced into the primary precious metals industry.

The technologically advanced process results in low operational costs enabling PRL to become a

novel in the field of PGM recovery from spent catalytic converters, and other appropriate waste

streams. This will be accomplished through of recovery rates and process development, to ensure

that the refining process is continually improved, thereby optimising throughput and recovery

rates.

Key Benefits of Platinum Recoveries Recovery Operations:

The only combined volume collection and refining operation for scrap auto-chemi- catalyst

Lower capital and operating costs combined with higher recovery rates than competing

technologies

Vitrified ceramic by product can be recycled as non leachable road aggregate

World class environmental performance (stable slag, low emissions)

Technically superior to competing technologies

PGM (Pt, Pd and Rh) Recovery

The process of recovering and refining precious metals is characterized by the following:

Quality: Thanks to an avant-garde industrial structure and the absolute thoroughness of the

recovery phases, the offered technology is capable of recovering gold, palladium, rhodium

and other precious metals from ashes and scrap / ingots of gold, gold sweepings, solutions,

slag, crucibles, catalysts from the chemical, petrochemical, and pharmaceutical industries,

catalytic converters, electronic waste, dental waste, and sludge.

The amounts and proportions of PGMs required per 1 ton vary but generally range from 2

to 4 kg of PGM per vehicle for cars, light-duty trucks, and motorcycles and 6 to 30 kg of

PGM for chemical and vehicles with larger engines, such as sport utility vehicles and

trucks.

Global Context

The technology basic induction thermal waste recovery facility and it represents the start of a revolutionary change

in the field of waste management.

The compact high intensity facility is equipped with the latest technology including a fully integrated emissions

abatement system and automated monitoring system for auditable environmental performance. The integrated

facility offers a valuable service to the car industry and is capable of servicing Original Equipment Manufacturers

(OEM) product lifecycle responsibilities. From a waste management standpoint it enables the integrated waste

management chain to comply with its 'duty of care' responsibilities.

The technology utilises a state-of-the-art high temperature induction smelting technology to

recover the PGMs, contained within the catalyst, as a concentrated metal alloy. This alloy is subjected to

further refining, before it is traded to re-enter the product supply chain, hence closing the recycling loop. This

exemplifies the environmental credentials of the technology as PGMs are a finite resource that are primarily

employed, in ever increasing quantities, to abate the emissions of fossil fuel powered vehicles. Therefore, PGM

recovery has massive environmental advantage. Furthermore, the slag product of the process; due to its inert

leaching resistant character, finds application as an aggregate in a wide range of traditional applications and the

metal casing are recycled using traditional routes.

As a consequence of this material reuse, the technology is observed to have minimal local environmental impacts,

and is classified as an Advanced Thermal Conversion Technique. This classification is applied due to the

technologies intermediate position within the waste management hierarchy, i.e. it is not a disposal or a recycling

technique, because the material values within the waste stream are recovered.
